Sony also confirmed the PlayStation 3 will use Blu-ray discs as its media format. The discs can hold up to six times as much data as current-generation DVDs. It will also support CR-ROM, CD-RW, DVD, DVD-ROM, DVD-R, DVD+R formats. Sony also confirmed the machine would be backward compatible all the way to the original PlayStation. It will also have slots for Memory Stick Duo, an SD slot, and a compact flash memory slot. It will also sport a slot for a detachable 2.5-inch HDD, somewhat similar the Xbox 360's. Sony did not mention if the drive would be standard.
Sony also laid out the technical specs of the device. The PlayStation 3 will feature the much-vaunted Cell processor, which will run at 3.2GHz, giving the whole system 2 teraflops of overall performance. It will sport 256MB XDR main RAM at 3.2GHz, and it will have 256MB of GDDR VRAM at 700MHz.
p
XBOX 360 is only capable of 1 teraflop by the way.
